T Shinomura - Journal of Plant Research, 1997 - SpringerSeed germination of many plant species is influenced by light. Of the various photoreceptor
systems, phyto- chrome plays an especially important role in seed germi- nation. The existence
of at least five phytochrome genes has led to the proposal that different members of the ...Cited by 50 - Related articles - BL Direct - All 2 versions

pool involved in the control of seed germination was investigated for Datura ferox seeds. These
seeds require both Pfr and alternating temperatures (20/30°C) to germinate. After 24 h ...Cited by 31 - Related articles - All 2 versions

JR Hilton - Planta, 1982 - SpringerAbstract. Seeds of Bromus sterilis L. germinated between 80-100% in darkness at 15 C but were
inhibited by exposure to white or red light for 8 h per day. Exposure to far-red light resulted in
ger- mination similar to, or less than, that of seeds maintained in darkness. Germination is ...Cited by 26 - Related articles
